Do you remember how, in days gone by, salesmen would go door
to door selling their wares? These entrepreneurs would “go
the extra mile” just to have the chance to demonstrate their
products to people in their own home.

The reason why door-to-door demonstrations of yesterday worked so well is because it gave the customer a chance to experience the product. Humans are experimental in nature. That is, we understand the world around us by experiencing it. So putting a product in our hands gives us that opportunity. We get to feel it, use it, and see how it’s application could benefit us.
